Portfolio theory moves us out of a linear logic of investment, which implies the steady securing of profit from long-term investment in certain concerns, towards a more chaotic and scattered pattern, which sees profit generated by overlapping, inter-referential, and even contradictory short-term investments as part of an overall portfolio and an overall strategy guided by the principle of securitization (see Chapter 3).
